How Much Does OnSIP Really Cost? A Complete Breakdown

OnSIP is a cloud-based VoIP provider that focuses on business phone system solutions. It offers essential features that businesses have come to expect, including auto attendants, call recording, voicemail boxes, and ring groups — and you can do it all while ditching desk phones if you choose. But what about OnSIP pricing?

While OnSIP is a fairly reliable business VoIP solution, it’s not the only one. Some customers may consider OnSIP alternatives that offer either more comprehensive solutions or better pricing — or both.

In this guide, we’ll break down exactly how OnSIP pricing plans work so you can determine if it’s the right fit for your business communication needs.

Overview of OnSIP Pricing Plans

OnSIP pricing is relatively straightforward. They offer three different plans, each with distinct features and price points. Let’s review the pricing and VoIP features available for each plan.

OnSIP pricing – Basic Plan: $49.95 per account per month

This plan is best for microteams, small businesses, or those who only need to facilitate internal communication. It does have some valuable features, but there are strict limitations on usage.

This plan does include:

• Three auto attendants
• Five voicemail-to-emails
• Three ring groups
• One call recording user
• Video conferencing

It does not include:

• Call minutes (a standard calling rate of 3.2 cents per minute applies)
• Call parking
• Busy lamp field (BLF)
• VoIP phones

This plan’s biggest limitation: its one-size-fits-all approach, which has relatively weak support for scaling or routing.

OnSIP pricing – Unlimited Plan: $18.95 per user per month (5 users minimum)

This per-user pricing plan, having fewer limitations, allows your team to scale more effectively than the previous option. It includes unlimited domestic calling, though only to select landlines in 21 countries.

It does include:

• Everything in the Basic Plan
• Unlimited number of auto attendants, call recording users, and ring groups
• Call parking
• VoIP phones
• BLF

This plan does have fewer limitations compared to the Basic Plan. However, it still lacks the features that some other cloud-based solutions may offer.

It does not include:

• Advanced call queues
• Skill-based routing
• Contact-center-grade features

OnSIP pricing – free plan: internal-only SIP calling

OnSIP offers a free plan, which includes internal-only SIP calling. You can’t make any external calls, but you can make internal calls with up to 100 users with web-to-web calling. Team members can make phone calls and video calls over OnSIP’s desktop app or mobile app.

This softphone solution is only viable for companies using SIP endpoints internally, which may include tech-heavy teams and remote teams.

Hidden Costs & Add-On Traps

OnSIP’s pricing seems competitive at first glance, especially when stacked up against competitors’ flat-rate pricing. It doesn’t seem so competitive, however, once you actually need business functionality.

While OnSIP’s site shows plenty of important VoIP phone service features are available, there are a slew of commonly needed features that you actually need to pay for as add-on products. These include:

• Auto-attendant menus: $19.95 per month
• Call recording: $4.95 per user per month
• Call parking lots: $14.95 per month for 15 channels
• Dial-by-name directory: $9.95 per directory
• Enhanced hold music: up to $19.95 per month
• Enhanced queues (ACD): $14.95 per agent seat per month
• Porting fees: $15 per number plus $2 per month
• E911 compliance: $1.80 per user per month

These costs can add up quickly if you need to pay for them, especially if you’re eyeing the basic option that doesn’t include call minutes. And when we say quickly, we really mean that.

The bottom line: A team of 10 using essential VoIP features could quickly push an $18.95 per user system to over $35 per-user per month without even touching call analytics, AI features, or CRM integrations.

That’s a high price to pay for a fairly simple solution, especially when many VoIP service providers offer more comprehensive or advanced features. And, in some cases, the contact center pricing works out to be more cost-effective when you account for the gained functionality.

Feature Gaps That Affect Growth

OnSIP may seem like a solid option for small teams on tight budgets. However, some significant feature gaps can impact your business’s growth if you plan to scale. It’s important to account for these.

Limited integrations

OnSIP has relatively limited integrations — only with Odoo, Zendesk, and HubSpot.

For those keeping track, this means they don’t integrate with commonly used platforms like:

• Salesforce
• Zoho
• Pipedrive
• Zapier
• Microsoft Teams

This can make workflow automation and unified CRM usage incredibly difficult, which can increase manual work and potentially result in increased errors.

Weak international calling support

OnSIP’s Unlimited Plan does support unlimited calling, but it’s restricted to 21 countries and landlines only.

It doesn’t offer bundled mobile or international rates. And while at first this doesn’t seem too bad of a trade-off for what appears to be a lower monthly flat fee, there’s a high risk of bill shock for teams dialing overseas frequently.

No analytics or automation

Many VoIP service providers today offer analytics or automation capabilities, especially if they’re integrated with call center software.

However, OnSIP has the following limitations:

• No call analytics or dashboard, unless you purchase them separately
• No call scoring, sentiment analysis, or agent monitoring features
• No AI-powered routing, transcription, or feedback loops

These features may seem unnecessary, especially for small businesses on tight budgets. However, they can each be essential to help sales and customer support teams improve their performance.

Not having these features — which can help you track how customers feel about their interactions or identify what changes you should make — can ultimately cost you customers and revenue in the long run.

No SMS/MMS or multichannel communication

OnSIP only offers voice and video calling. This means there’s no native SMS, email, live chat, or social media functionality.

This isn’t an omnichannel tool, which can be incredibly restrictive on businesses of all sizes today, especially since most customers now expect a seamless omnichannel experience that allows them to communicate with brands on their preferred platforms.

Who OnSIP Works For

OnSIP does work for some teams. These may include:

• Tech-savvy teams using SIP endpoints for internal communications
• Micro-businesses that truly only need voicemail and extremely basic interactive voice response (IVR) systems
• Startups that want a cheap, entry-level VoIP and don’t need plans for scaling or external integrations

If your company doesn’t fit into any of these profiles, that’s okay; other platforms are likely a much better fit.

Final Takeaway: Is OnSIP Worth It?

If your team truly only needs internal SIP-to-SIP calls or bare-bones features for a few dollars a month, OnSIP is functional. This is why there are plenty of reviews online from happy OnSIP customers. It’s a reliable service if that’s what you need.

But for most SMBs and scaling teams, the math simply doesn’t work out in OnSIP’s favor, not once you consider all the add-on products and nonexistent features, which have substantial real-world costs.

That’s why so many businesses of all sizes are looking at comprehensive communication platforms. And that’s what brings so many businesses to Nextiva.

Nextiva offers a modern, cloud-based, AI-powered communications solution with everything bundled in right from the start. There are no hidden add-ons and no vendor lock-ins — just clear pricing, built-in scalability, and round-the-clock support.
